[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a water-cooled protective structure for a photovoltaic power generation energy storage battery, including a protective box 1, an inlet pipe 4 fixedly connected to one side of the protective box 1 for introducing coolant into a cooling pipe 5, a heating component inside the protective box 1, an outlet pipe 8 fixedly connected to one side of the protective box 1 for discharging coolant out of the cooling pipe 5, and a heat dissipation component inside the protective box 1.

[0032] The heat dissipation assembly includes multiple cooling pipes 5, a first connecting pipe 6, and a second connecting pipe 7. The multiple cooling pipes 5 are installed inside the protective box 1 to dissipate heat from the battery 2. One end of one cooling pipe 5 is fixedly connected to one end of the liquid inlet pipe 4. One end of the first connecting pipe 6 is fixedly connected to one end of the cooling pipe 5 for vertical connection. One end of the second connecting pipe 7 is fixedly connected to one end of the cooling pipe 5 for horizontal connection. The heat generation assembly includes the battery 2 and a heat-conducting plate 3. The bottom of the multiple batteries 2 is fixedly connected inside the protective box 1 to store the generated electrical energy. One side of the heat-conducting plate 3 is fixedly connected to one side of the battery 2 to conduct heat into the cooling pipes 5 for heat dissipation.

[0033] Specifically, the coolant first slowly enters the first cooling pipe 5 through the inlet pipe 4. Then, it is introduced from the end of the cooling pipe 5 into the second cooling pipe 5 through the connecting pipe 6. Next, the coolant is introduced from the end of the cooling pipe 5 into the connecting pipe 7. Then, it continues to flow into the interior of the third cooling pipe 5. After that, the coolant flows into the other connecting pipe 6 at the end and then into the fourth cooling pipe 5. Finally, it is introduced into the interior of the second connecting pipe 7, thus completing one cycle and preparing to enter the next cycle.

[0034] Reference Figure 3 A fan 9 is fixedly connected to one side of the protective box 1 for cooling the water tank 11. One end of the outlet pipe 8 is fixedly connected to a return pipe 10 to guide the coolant back to the water tank 11. The other end of the return pipe 10 is fixedly connected to the water tank 11 for storing the coolant. Multiple cooling fins 12 are fixedly connected to the outer wall of the water tank 11 to dissipate the heat absorbed by the coolant. A water outlet pipe 13 is fixedly connected to one side of the water tank 11. The cooling fins 12 are arranged in a parallel array and fixedly connected to the outer wall of the water tank 11. A water pump 14 is fixedly connected to one end of pipe 13 to provide power for the circulation of coolant. The input end of water pump 14 is connected to the outlet pipe 13, and the output end of water pump 14 is connected to the inlet pipe 4. Each cooling pipe 5 is arranged in a parallel array and fixedly connected to one side of heat conduction plate 3. Connecting pipe 1 6 is arranged in a parallel array and fixedly connected to one end of multiple cooling pipes 5. Connecting pipe 2 7 is arranged in a parallel array and fixedly connected to the other end of multiple cooling pipes 5. One end of outlet pipe 8 is fixedly connected to one end of one of the cooling pipes 5.

[0035] Specifically, the fan 9, located between the water tank 11 and the protective box 1, directs its airflow towards the water tank 11. This not only provides heat dissipation for the surface of the protective box 1 but also blows air onto the water tank 11 for heat dissipation. At this time, the coolant inside the water tank 11 flows out from the outlet pipe 13 and then enters the water pump 14, where it is guided into the cooling pipe 5. After that, the coolant is discharged from the cooling pipe 5 and enters the return pipe 10. Finally, it returns to the water tank 11. After being cooled by the cooling fins 12 inside the water tank 11, a new cycle begins.

[0036] Working principle: In the process of using the water-cooled protective structure of the photovoltaic power generation energy storage battery, after the equipment is installed, coolant is added to the water tank 11, and then the water pump 14 is started. The coolant is then discharged from the outlet pipe 13 and introduced into the inlet pipe 4. It slowly enters the first cooling pipe 5 through the inlet pipe 4, and then from the end of the cooling pipe 5 through the connecting pipe 1 6 into the second cooling pipe 5. Next, the coolant is introduced into the connecting pipe 2 7 at the end of the cooling pipe 5, and then it continues to flow into the interior of the third cooling pipe 5. After that, the coolant flows into the end again. Another connecting pipe 6 enters the fourth cooling pipe 5, and finally, it is guided into the second connecting pipe 7, thus completing one section of the cycle and preparing to enter the next section of the cycle. When the last section is reached, it flows from the fourth cooling pipe 5 into the outlet pipe 8, and then from the outlet pipe 8 into the return pipe 10, so that the coolant returns to the water tank 11, thus completing the entire coolant circulation process. After a period of use, because the heat dissipation efficiency of the water tank 11 is insufficient, the fan 9 is turned on to blow air to increase the heat dissipation efficiency of the water tank 11 and the cooling fins 12.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
